Answer:
2KClO3 —> 2KCl + 3O2
The coefficients are 2, 2, 3
Explanation:
From the question given above, we obtained the following equation:
KClO3 —> 2KCl + 3O2
The above equation can be balance as follow:
There are 2 atoms of K on the right side and 1 atom on the left side. It can be balance by putting 2 in front of KClO3 as shown below:
2KClO3 —> 2KCl + 3O2
Now, the equation is balanced.
Thus, the coefficients are 2, 2, 3
Answer:
Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.
Sodium is a metal and bromine is a nonmetal so they form an ionic compound
nonmetals and nonmetals form covalent compounds
The energy of the electron reduces as it moves closers to the nucleus. This is because it moves from a higher energy orbital to a one of lower energy. It does this by releasing a photon with the energy difference of the current energy level, and the energy level it drops too.
,Answer:
kinetic energy, gamma decay, it becomes less stable by repositioning its particles
